[0002] At present, in the production of electronic products, the workpiece (such as a mobile phone housing, etc.) is positioned by a jig.

[0063] The technical solution of the present application will be described below in conjunction with the drawings in the implementation modes of the present application. Obviously, the described implementation modes are only part of the implementation modes of the present application, rather than all the implementation modes.

[0065] In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance. The term "perpendicular" is used to describe an ideal state between two components. In actual production or use, there may be a state that is approximately perpendicular between the two components. For example, in combination with numerical descriptions, perpendicularity may refer to the angle between two straight lines being in the range of 90°±10°, perpendicularity may also refer to the dihedral angle between two planes being in the range of 90°±10°, and perpendicularity may also refer to the angle between a straight line and a plane being in the range of 90°±10°. The two components described as "perpendicular" may not be absolute straight lines or planes, but may be roughly straight lines or planes. From a macroscopic perspective, a component can be considered a "straight line" or a "plane" if the overall extension direction is a straight line or a plane.
[0066] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.
[0067] At present, in the production of electronic products, the workpiece (such as a mobile phone housing, etc.) is positioned by a jig. When the gripper of the robot arm needs to take the workpiece from the jig, the jig must first release the positioning of the workpiece before the gripper can take the workpiece. The jig has a socket, and the gripper is provided with a latch. The jig can release the positioning of the workpiece after the gripper inserts the latch into the socket. Usually, the gripper and the latch are rigidly connected. When the latch and the socket are not fully aligned or slightly offset, the jig will generate a large force on the latch during the insertion of the latch into the socket. This force will directly act on the robot arm, affecting the service life of the robot arm.
[0068] In one embodiment of the present application, a floating latch is provided, including a fixed seat, a floating seat, a reset member, a deflection member and a pin head. A cavity is formed inside the fixed seat, the floating seat is partially accommodated in the cavity, the floating seat can rotate and move relative to the fixed seat, the reset member is provided at the fixed seat and the floating seat, the reset member can reset the floating seat relative to the fixed seat, the deflection member includes a first rotating shaft for being pivotally connected to the floating seat, the deflection member can swing around the first rotating shaft relative to the floating seat, the pin head includes a second rotating shaft for being pivotally connected to the deflection member, the pin head can swing around the second rotating shaft relative to the deflection member, and the second rotating shaft is perpendicular to the first rotating shaft.
[0069] When the above-mentioned floating latch is in use, since the floating seat can rotate and move relative to the fixed seat, and the pin head can swing along the first and second rotating axes that are perpendicular to each other, the pin head has the freedom to move and rotate in space. In the process of inserting the pin head into the socket, even if the pin head and the socket are not aligned or there is a deviation, the pin head will offset it through movement and rotation, so that the pin head can be accurately inserted into the socket, thereby increasing the service life of the robotic arm and the success rate of inserting the pin head into the socket.
[0070] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0071] See also Figure 1 In one embodiment of the present application, a floating latch 100 and a processing device 200 are provided. The processing device 200 includes a fixture 201, a gripper 202 and a floating latch 100. The fixture 201 is used to position a workpiece. The fixture 201 is provided with a socket 203. The floating latch 100 is provided on the gripper 202. The gripper 202 is used to drive the floating latch 100 to move in space so that the floating latch 100 is inserted into the socket 203. When the floating latch 100 is inserted into the socket 203, the positioning of the workpiece by the fixture 201 can be released so that the gripper 202 can take the workpiece away from the fixture 201.
[0072] As a further illustrative example, the processing equipment 200 also includes a robotic arm (not shown), and the gripper 202 is disposed on the robotic arm, and the robotic arm is used to drive the gripper 202 to move in space.
[0073] See also Figures 2 to 4In some embodiments, the floating latch 100 includes a fixed seat 10, a floating seat 20, a reset member 30, a deflection member 40 and a pin head 50. The fixed seat 10 is disposed on the gripper 202 and is fixed relative to the gripper 202. The floating seat 20 is a rotating body and is disposed on the fixed seat 10. The floating seat 20 can rotate relative to the fixed seat 10 around the axial direction of the floating seat 20 (Z direction, i.e., the direction of gravity) and move along the radial direction of the floating seat 20 (the direction in the XY plane, i.e., the horizontal direction). The reset member 30 is disposed on the fixed seat 10 and the floating seat 20. The reset member 30 is used to reset the floating seat 20 relative to the fixed seat 10. The deflection member 40 is disposed on the floating seat 20. The deflection member 40 can swing relative to the floating seat 20 around the first radial direction (X direction) of the floating seat 20. The pin head 50 is disposed on the deflection member 40 , and the pin head 50 can swing relative to the deflection member 40 around the floating seat 20 in a second radial direction (Y direction), and the second radial direction (Y direction) is perpendicular to the first radial direction (X direction).
[0074] When the floating pin 100 is inserted into the socket 203, since the floating seat 20 can rotate around the Z direction and move in the direction of the XY plane relative to the fixed seat 10, and the pin head 50 can swing around the X direction and the Y direction, the pin head 50 has the freedom to move in the XY plane and the freedom to rotate around the X, Y, and Z directions. During the process of inserting the pin head 50 into the socket 203, even if the pin head 50 and the socket 203 are not aligned or there is a deviation, it will be offset by the movement and rotation of the pin head 50, so that the pin head 50 can be accurately inserted into the socket 203, thereby improving the success rate of the pin head 50 inserting into the socket 203. In addition, the force exerted by the fixture 201 on the pin head 50 will also be offset by the movement and rotation of the pin head 50, thereby avoiding the force from acting on the gripper 202 or the robotic arm, thereby improving the service life of the gripper 202 and the robotic arm.
[0075] In some embodiments, a cavity 11 is formed inside the fixed seat 10, and the floating seat 20 is partially located in the cavity 11. The floating pin 100 also includes a lubricating member 60, which is disposed in the cavity 11 and between the floating seat 20 and the fixed seat 10. The lubricating member 60 is used to reduce the friction between the floating seat 20 and the fixed seat 10, and facilitates the rotation of the floating seat 20 around the Z direction and the movement in the XY plane, thereby improving the response speed and response efficiency of the floating seat 20.
[0076] In some embodiments, the floating seat 20 includes an inner disk 21, a connecting shaft 22 and an outer disk 23 which are coaxially arranged. The connecting shaft 22 is connected between the inner disk 21 and the outer disk 23. The inner disk 21 is located in the cavity 11, the outer disk 23 is located outside the cavity 11, and the deflection member 40 is arranged on the outer disk 23. The fixed seat 10 is provided with a through hole 12 which connects the cavity 11 with the outside of the cavity 11. The connecting shaft 22 passes through the through hole 12. The radial dimension of the through hole 12 is larger than the radial dimension of the connecting shaft 22, so as to allow the floating seat 20 to move in the XY plane relative to the fixed seat 10. The lubricating member 60 is arranged between the inner disk 21 and the fixed seat 10. When the floating seat 20 moves or rotates relative to the fixed seat 10, the inner disk 21 can reduce the friction with the cavity wall of the cavity 11 through the lubricating member 60, so as to facilitate the movement or rotation of the floating seat 20.
[0077] In some embodiments, in order to facilitate the assembly of the floating seat 20 and the fixed seat 10, the fixed seat 10 includes a cover body 13 and a plate body 14, the cover body 13 is detachably arranged on the plate body 14, the cavity 11 is formed between the cover body 13 and the plate body 14, and the through hole 12 is arranged on the plate body 14. During assembly, the coupling shaft 22 is first passed through the through hole 12 and the inner disk 21 is located above the plate body 14, and the lubricating member 60 is installed at the same time, and then the cover body 13 is installed on the plate body 14, so that the inner disk 21 and the lubricating member 60 are installed in the cavity 11.
[0078] Optionally, the reset member 30 is provided between the plate body 14 and the outer disk 23, and the reset member 30 resets the outer disk 23 relative to the plate body 14 to reset the floating seat 20 relative to the fixed seat 10. In other embodiments, the reset member 30 may also be provided between the plate body 14 and the inner disk 21, and the reset member 30 resets the floating seat 20 relative to the fixed seat 10 by resetting the inner disk 21 relative to the plate body 14. The resetting of the floating seat 20 relative to the fixed seat 10 refers to the position of the floating seat 20 relative to the fixed seat 10 when the reset member 30 returns to the natural state, for example, when the reset member 30 returns to the natural state, the axis of the floating seat 20 coincides with the axis of the fixed seat 10, and the floating seat 20 is reset relative to the fixed seat 10 at this time.
[0079] Optionally, the cover body 13 includes a connected barrel 131 and a top plate 132, the top plate 132 and the plate body 14 are circular, the outer diameter of the barrel 131, the outer diameter of the plate body 14 and the outer diameter of the top plate 132 are the same, the top plate 132 is coaxially arranged at the top of the barrel 131, and the plate body 14 is coaxially arranged at the bottom of the barrel 131, so that the cavity 11 is cylindrical, and the diameter of the cavity 11 is larger than the diameter of the inner disk 21, so as to allow the inner disk 21 to move along the XY plane in the cavity 11.
[0080] In some embodiments, the lubricating member 60 includes two ball retainers 61 and a plurality of balls 62. The two ball retainers 61 are respectively arranged on opposite sides of the inner disk 21 along the Z direction, that is, the two ball retainers 61 are respectively arranged above and below the inner disk 21. Each ball retainer 61 is provided with a plurality of accommodating holes 611 distributed at intervals. Each accommodating hole 611 is used to accommodate a ball 62. The ball 62 can roll between the inner disk 21 and the cavity wall of the cavity 11. The ball retainer 61 limits the positions of the plurality of balls 62 through the accommodating holes 611 to prevent the plurality of balls 62 from rolling randomly and gathering in large quantities on one side of the inner disk 21, resulting in lubrication failure. The balls 62 turn the friction between the inner disk 21 and the cavity wall of the cavity 11 into rolling friction by rolling, thereby reducing the friction force.
[0081] In some embodiments, the ball retainer 61 has the same outer diameter as the inner disk 21, and each ball retainer 61 has six receiving holes 611, which are evenly distributed along the circumference of the ball retainer 61, thereby making the lubrication between the inner disk 21 and the wall of the cavity 11 more uniform.
[0082] In some embodiments, the ball 62 located above the inner disk 21 always contacts the top surface of the inner disk 21 and the wall of the cavity 11, and the ball 62 located above the inner disk 21 always contacts the bottom surface of the inner disk 21 and the wall of the cavity 11, thereby restricting the movement of the inner disk 21 along the Z direction, preventing the inner disk 21 and even the floating seat 20 from shaking along the Z direction, and improving the stability of the floating seat 20 along the Z direction.
[0083] In some embodiments, in order to facilitate the processing of the receiving hole 611, the receiving hole 611 of the ball retainer 61 is a through hole with a fixed diameter, and the diameter of the receiving hole 611 is equal to the diameter of the ball 62. It can be understood that in order to ensure rolling friction between the inner disk 21 and the cavity wall of the cavity 11, the thickness of the ball retainer 61 needs to be smaller than the diameter of the ball 62, otherwise the ball retainer 61 will contact the inner disk 21 and the cavity wall of the cavity 11, resulting in sliding friction between the ball retainer 61, the inner disk 21 and the cavity wall of the cavity 11, causing lubrication failure. Therefore, when the diameter of the receiving hole 611 is equal to the diameter of the ball 62, and the thickness of the ball retainer 61 is less than the diameter of the ball 62, the ball retainer 61 located above the inner disk 21 will inevitably contact the inner disk 21 below under the action of gravity, and the ball retainer 61 located below the inner disk 21 will inevitably contact the plate body 14 under the action of gravity, resulting in sliding friction between the upper ball retainer 61 and the inner disk 21, and between the lower ball retainer 61 and the plate body 14. In order to reduce this sliding friction, the bottom of each ball retainer 61 has a plurality of protrusions 612, which can reduce the contact area between the ball retainer 61 and the inner disk 21 and the plate body 14, thereby reducing sliding friction and improving lubricity.
[0084] In addition, the protrusion 612 can also raise the height of the ball retainer 61, so that the center of the ball retainer 61 is closer to the center of the ball 62, so that the ball retainer 61 can more stably limit the ball 62 and prevent the ball 62 from shaking in the receiving hole 611. Therefore, the protrusion 612 can also allow the thickness of the ball retainer 61 to be appropriately reduced to reduce the weight of the ball retainer 61, as long as the ball retainer 61 can play a role in limiting the ball 62. Preferably, the height of the protrusion 612 can raise the center of the ball retainer 61 to be in the same plane as the center of the ball 62, thereby improving the stability of the hole wall of the receiving hole 611 in limiting the ball 62.
[0085] Optionally, the protrusion 612 is a cylinder, the bottom surface of which contacts the inner disk 21 and the plate body 14, or the protrusion 612 is a hemisphere, the lowest point of which contacts the inner disk 21 and the plate body 14, so that the contact between the protrusion 612 and the inner disk 21 and the plate body 14 becomes a point contact, thereby reducing friction.
[0086] In some embodiments, Figures 4 to 6 As shown, the two ball retainers 61 are both disc-shaped and are divided into an upper ball retainer 61a and a lower ball retainer 61b. Since the lower ball retainer 61b is located below the inner disk 21, the lower ball retainer 61b needs to be provided with a through hole 61b1, and the through hole 61b1 is used for the connecting shaft 22 to pass through. Due to the existence of the through hole 61b1, the distribution radius of the six receiving holes 611 of the lower ball retainer 61b must be larger than the radius of the through hole 61b1, otherwise the ball 62 will fall from the through hole 61b1. Since the upper ball retainer 61a is located above the inner disk 21 and does not need to avoid the connecting shaft 22, the distribution radius of the six receiving holes 611 of the upper ball retainer 61a can be smaller than the distribution radius of the six receiving holes 611 of the lower ball retainer 61b, so that the receiving holes 611 can be further away from the edge of the upper ball retainer 61a, avoiding the thickness between the edge of the upper ball retainer 61a and the hole wall of the receiving holes 611 being too small, thereby improving the structural strength of the upper ball retainer 61a. It can be understood that in other embodiments, the distribution radius of the six receiving holes 611 of the upper ball retainer 61a can be equal to the distribution radius of the six receiving holes 611 of the lower ball retainer 61b, as long as the structural design can be met.
[0087] See also Figure 8In other embodiments, the receiving hole 611 of the ball retainer 61 is not a through hole with a fixed diameter, but a hole with a variable diameter. The hole wall of the receiving hole 611 can fully contact the ball 62, which not only limits the position of the ball 62 more stably, but also limits the height of the ball retainer 61, so that the ball retainer 61 cannot contact the inner disk 21 and the plate body 14 under the action of gravity, and thus the friction between the inner disk 21 and the cavity wall of the cavity 11 is completely rolling friction. In this case, the bottom of the ball retainer 61 does not need to be provided with a protrusion 612.
[0088] Alternatively, see Figure 7 In other embodiments, a plurality of grooves 211 are provided on the top and bottom surfaces of the inner disk 21, and each groove 211 is used to accommodate a ball 62 and limit the position of the ball 62. In this case, there is no need to provide a ball retainer 61, and the friction between the inner disk 21 and the wall of the cavity 11 can be completely rolling friction.
[0089] See also Figures 3 to 5 In some embodiments, the reset member 30 includes a plurality of first magnetic members 31 and a plurality of second magnetic members 32. The plurality of first magnetic members 31 are disposed on the plate 14 of the fixed seat 10, and the plurality of second magnetic members 32 are disposed on the outer disk 23 of the floating seat 20. The plurality of first magnetic members 31 and the plurality of second magnetic members 32 are evenly distributed around the Z direction, and each first magnetic member 31 is opposite to and attracted to a second magnetic member 32 along the Z direction. In the initial state, the second magnetic member 32 will be stabilized at the position closest to the first magnetic member 31 under the magnetic attraction of the first magnetic member 31. When the floating seat 20 moves or rotates relative to the fixed seat 10, the second magnetic member 32 will move away from the position closest to the first magnetic member 31 with the floating seat 20. When resetting, the second magnetic member 32 will return to the position closest to the first magnetic member 31 under the magnetic attraction of the first magnetic member 31, thereby achieving the reset of the floating seat 20.
[0090] In other embodiments, the reset member 30 may also be a plurality of springs, with both ends of the springs connected to the plate body 14 and the outer disk 23 , and the springs achieve the reset of the floating seat 20 by pulling the outer disk 23 .
